SPECIFICATION forming part of Letters Patent No. 492,631, dated February28, 1893.

Application filed April 15, 1892. Serial No. 429,305. on. model.)

To all whom it may concern.-

Be it known that I, JOHN PIOKERING, of New York city, in the county andState of New York, have invented a new and Improved Disinfecting Device,of which the following is a full, clear, and exact description.

My invention relates to improvements in disinfecting devices; and theobject of my invention is to produce a cheap and simple device intowhich a quantity of disinfecting material may be placed and which, whenplaced in position in a tank such as is used for flushing purposes andespecially with such tanks as are used for flushing water closets, willat every discharge of the tank eject a suflicient quantity ofdisinfecting solution into the water to thoroughly disinfect the bowl orother article to which the water is'supplied.

To this end my invention consists in adisinfecting device, theconstruction of which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

, Figure l is a central vertical section of the entire device. Fig. 2 isa sectional plan of the same on the line 22 in Fig. 1. Fig. 3 is anenlarged detail view of the valve mechanism of the device. Fig. 4 is anenlarged elevation of the float frame which operates the valve; and Fig.5 is a sectional elevation of the flushing tank provided with theimproved device.

The flask or vessel in which the disinfecting compound is held, isprovided with a flat base 11 to enable it to rest firmly on the tankbottom and it has in the bottom an aperture closed by a plug or stopper12 through which the disinfecting compound is inserted. The flask isfilled with any suitable disinfecting compound, preferably of acrystalline character, and after the compound is inserted, the plug orstopper 12 is cemented in place so as to hermetically seal theflask. Inone side of the flask or vessel is a vent 13 which permits the ingressor egress of air, to the end that sufficient water may flow in and outof the flask, and a pipe 14 is inserted into one side of the flask nearthe bottom, the pipe having a reduced inner end 15 which extends intothe flask and which is perforated to permit the water to pass in or outthrough it. A seat 16 is formed at the outer end of the reduced portion15, as shown in Fig. 3, and a valve 17 is held to close against thisseat, a ball valve like that shown in the drawings being preferablyemployed, although other kinds of valves may be substituted. The valveis secured to a rod 18 which projects outward beyond the side of theflask and is adapted to engage a cross rib 19 on the swinging frame 20which is pivoted at its lower end to a lug 21 on the side of the flask,and which has at its free end a float 22 which causes it to swing upwardwith the rise of water in the tank.

When the device is to be used, it is placed upon the bottom of the tank23 which has a flushing pipe 24 opening therefrom, the outlet beingcontrolled by a valve25 and a float 26 in the usual manner, but it willbe understood that any variety of tank may be used which is adapted tobe alternately emptied and filled to flush any other vessel.

The operation of the device is as follows When the tank 23 is beingemptied, the frame 20 will drop down and the valve 17 will pass from itsseat so as to allow all the solution in the flask to run out and passoff with the water. When the tank is again being filled, the float 22will rise with the water and swing the frame 20 against the rod 18 so asto close the valve, but before the valve closes water will pass inwardthrough the pipe 1& and sufficient will enter the flask or vessel inthis Way to dissolve aportion of the crystalline compound.

therein, so that at each operation'enough disinfecting solution willpass into the tank water to have the required disinfecting effect. Byregulating the size of the pipe 14 and its inner perforated end and theheight of the vent 13, just the required amount of solution may be madeto issue from the flask at each operation of the valve mechanism, thisoperation taking place at the last partof the flush or flow from thetank, and the disinfecting solution remains in the bowl and trap of thecloset until again used; the same applies to any article to which theWater is supplied.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with a tank, of a vesselcontaining a soluble disinfectant and provldedat or near its bottom withan opening controlled by a float-operated valve, said vessel beingsupportedin the tank with its openlng below the water level of saidtank, whereby provision is made for allowing the water from the tank toflow into the vessel to dissolve the disinfectant while the tank isbeing filled, and the dissolved disinfectant permitted to flow out ofthe vessel into the tank when the said tank is being emptied, as setforth.

2. The combination with a tank, of a vessel containing a solubledisinfectant supported upon the bottom of the tank and provided wlth avent a short distance from its bottom and with an opening at its bottom,said open.- in g being controlled by a float operated valve,

' substantially as and for the purpose set forth.

3. A disinfecting device, comprising aflask having a vent in one sideand a pipe near the bottom, the pipe having a reduced and perforatedinner end which extends into the flask, a .valve held in the pipe andhaving an outwardly extending stem, and a swinging float frame hingedbeneath the pipe and adapted to come in contact with the valve stem,substantially as described.

4. A disinfecting device comprising a fiat bottom flask having astopper-closed opening therein, a vent in one side, a pipe near itslower end, a valve held to close the pipe and having an outwardlyextending stem, and a swinging float frame pivoted below the pipe andadapted to engage the outer end of the valve stem, substantially asdescribed.
